Cylinder cleaning device and cylinder cleaning fabric used therefor

Abstract

Divided shaft members constitute a cleaning fabric take-up shaft, and are secured at both ends by shaft member fixing means that is attached to a side plate. Shaft member fixing portions include a shaft end supporter, for supporting the end of the shaft member; and a plug that is fitted to a shaft receiving section. A wedge portion is provided, which runs across the center of the shaft end supporter and is projected linearly. When this wedge portion is inserted between the shaft members, the diameter of the shaft is increased. At this time, the winding of the cleansing fabric is performed. To dispose of the wound cleaning fabric, the shaft members are detached from the shaft member fixing portions and the wedge is extracted from the shaft members, so that the diameter is reduced, and the cleaning fabric is disengaged from the shaft members. As a result, the cleaning fabric take-up shaft can be removed from the cleaning fabric roll.
